[0020] like Figures 1-2 As shown, a self-made disposable flushing and drainage device includes at least one three-way connector 1. Multiple three-way connectors 1 are connected in series via connecting pipes 2. A suction tube 3 is inserted into one port 13 of the three-way connector 1. A flushing tube 4 is provided inside the suction tube 3. The front ends of the suction tube 3 and the flushing tube 4 are placed into the patient's wound 5. The wound 5 is covered and sealed with a transparent dressing 6. The rear end of the flushing tube 4 extends out of the suction tube 3 and is connected to a flushing connector 7. In actual application, the flushing connector 7 can be connected to the infusion tube of the flushing infusion set. A drainage tube 8 is inserted into the remaining port of the three-way connector 1 at the end. The drainage tube 8 is connected to a drainage bottle 9. The drainage bottle 9 is connected to a negative pressure source 10 via a pipeline. A reserved tube 11 is inserted into the remaining port 13 of the three-way connector 1 at the end. A water-stopping clamp 12 is provided on the reserved tube 11. By designing a three-way connector 1, drainage tube 8, suction tube 3, and transparent dressing 6, negative pressure drainage of the wound can be achieved. By designing an irrigation tube 4 and irrigation connector 7 on the suction tube 3, irrigation of the wound can also be achieved. By connecting multiple three-way connectors 1 in series using connecting tube 2, irrigation and drainage of multiple wounds can be achieved. The overall connection uses a plug-in method, which is simple to operate and particularly suitable for self-made applications. Moreover, these components can be obtained from existing hospital double-plug infusion sets and scalp vein needles, resulting in low cost and reducing the economic burden on patients.

[0021] The aforementioned three-way connector 1, connecting tube 2, drainage tube 8, reserved tube 11, and water-stop clamp 12 can be manufactured using existing double-plug infusion sets. Existing double-plug infusion sets (also called dual-head infusion sets) include a double plug and double connector (used as a three-way connector 1), an infusion tube (which can be used as a drainage tube 8, connecting tube 2, and reserved tube 11), and a water-stop clamp 12 (some use a speed limiting valve, which can replace the water-stop clamp 12).

[0022] The flushing tube 4 and flushing connector 7 are made using existing scalp needles. Existing scalp needles include a needle tube (used as flushing tube 4) and a plastic tube (used as flushing connector 7) for connecting the delivery tube.

[0023] The above specific embodiments should not be construed as limiting the scope of protection of the present invention. For those skilled in the art, any alternative improvements or modifications made to the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0024] Any aspects of this invention not described in detail are well-known to those skilled in the art.
